PPU: basic cache #19

Closed fengb closed 5 years ago

fengb commented 5 years ago

Depends on https://github.com/fengb/fundude/issues/18

Immediately propagate VRAM changes into ppu.patterns
Mark entire background/window/spritesheet as dirty
During ppu.step, only rerender background/window/spritesheet if dirty

Patterns are a lot bigger than I had remembered (128-bits). I think it deserves the same tile-based-cache as background/window/spritesheet. Thus this is only rudimentary "cache all"

Super simple dirty checks actually improved render time by a lot. Marking this resolved and moving the hard stuff to other issues.
